Double accents with windowsless = false

Hi, 

After setup silverlight object with param WindowsLess = false, I'm getting double accents on my app i.e.: "á" change to "´´a", "â" change to "^^a", and so on...!

I read many solutions for this, changing param WindowsLess = true.

The problem is, after change the parameter, no HTML over silverlight should be possible, on any other browser than Internet Explorer. 

Try to find a solution on this post, but the Issue haven't been solved yet!

This is a very strange behavior, and I need to get a solution quickly!

Many tx, 

Regards!
